  • Publication number: 20200247062
    Abstract: A computer-controlled system for forming composition-controlled objects using 3D printing includes two or more liquid reactant reservoirs, and a mixing sub-system for mixing the two or more liquid reactant compositions, which in turn includes a flow control sub-system to control a mass ratio of the mixed two or more liquid reactant compositions. The computer-controlled system further includes a scanning sub-system that, under control of the computer, causes relative motion of a mixed liquid reactants nozzle over a substrate; thereby depositing the mixed liquid reactant compositions onto the substrate. The system still further includes an illuminations system, operated under control of the computer, to polymerize the deposited mixed liquid reactant compositions.

  • Patent number: 10545214
    Abstract: An electron paramagnetic resonance device includes a crystalline, emission-sensitive mass and a housing containing the device. The mass includes structurally incorporated carbonate content in a range of about 3% by weight to about 10% by weight of the mass, one or more structurally incorporated non-calcium metallic cations, and one or more structurally incorporated phosphate anions. When irradiated with a known source, the EPR device may function as a reference. When unirradiated, the EPR may function as a dosimeter. As a dosimeter, the EPR device may be used as a personal dosimeter or as a monitor for inanimate objects being subjected to radiation sources. The EPR dosimeter may be used for both gamma radiation and neutron radiation measurements.
